Definitions
- the invention relates to a device for the central supply of several cleaning systems with cleaning fluid with a dosing device with a detergent reservoir and with a water inlet and with a receiving container that holds the detergent-water mixture.
- Dosing stations of this type essentially consist of a storage container for the powder detergent, a water inlet and a flushing funnel in which the detergent is formed from a water / detergent mixture, and a storage container for the detergent.
- the detergent or the powdered detergent is placed in the corresponding storage container, depending on the desired detergent concentrate, a certain amount of detergent is added to the induction funnel, into which water is simultaneously introduced.
- the resulting detergent-water mixture flows into the storage container, from which it is pumped to the appropriate customers (dishwashers or washing machines).
- the invention is therefore based on the object of providing a central metering station for supplying cleaning systems with a suspension containing cleaning agents, in which powdered cleaning agent is kept and processed in such a way that non-dissolving particles are kept freely suspended in the suspension and the suspension can be supplied to individual cleaning systems at any time.
- this object is achieved according to the invention in that the storage container with an agitator with flow baffles for producing a cleaner suspension from the introduced cleaner-water mixture provided and a ring line starting from the storage container and flowing back into this is provided with continuous pumping around of the detergent suspension generated.
- This design makes it possible to supply a large number of individual cleaning machines with a cleaning suspension with finely divided cleaning particles of small diameter.
- This detergent suspension is generated from the detergent-water mixture initially introduced into the storage container by generating shear forces in the storage container by means of the agitator and the flow baffles and is maintained accordingly.
- the continuous pumping process in the ring line ensures that the detergent particles cannot settle and clump in the line, so that each individual cleaning system can be supplied with detergent suspension as required. If no detergent suspension is removed, the suspension is pumped back into the reservoir and reprocessed there accordingly.
- the invention provides that the flow baffles are formed by at least one fixed whisk bar.
- a dosing device 1 with a detergent storage container 2, a water inlet 3 and a flushing funnel 4 is connected to a storage container 5.
- the storage container 5 has an agitator 6 and a whisk bar 7. Via a ring line 8 and a centrifugal pump 9, the cleaning liquid pumped to consumers 10.
- the ring line 8 opens back into the storage container 5.
- the mode of action is as follows: The powdered cleaner is placed in the storage container 2 of the metering device 1. Depending on the dosage, the cleaner and the water that enters from the water inlet 3 enter the induction hopper 4. In this induction hopper 4, the detergent is slurried and flows as a dispersion into the storage container 5.
- This cleaning dispersion is stirred in the storage container 5 with the stirrer 6.
- a whisk bar 7 is provided. The combination of agitator 6 and whisk bar 7 creates a turbulent flow profile in the reservoir. Due to the shear effect on the dispersing particles, a connection of these particles is prevented and the particle size is reduced. This produces a cleaner suspension, so that clumping of the cleaner particles becomes impossible.
- the cleaner suspension is pumped to the consumers 10 (washing machines or dishwashers) by means of the centrifugal pump 9 through the ring line 8 via a check valve, which prevents the backflow of the cleaner suspension into the storage container 5.
- the one that has not been removed from consumers 10 Detergent suspension is pumped back into the reservoir 5 via a solenoid valve 2. This constant conveyance of the detergent suspension in the ring line 8 prevents the detergent particles from settling. Further features of the dosing station, not shown in the drawing, are described below:
- the fill level in the reservoir 5 is monitored by a level control. If the level of the detergent suspension drops below a certain level (amount less than 10 1), the storage container 5 is refilled via the metering device 1.
- the reservoir 5 is dimensioned such that at least 30 l of detergent suspension remain even at a minimal fill level.
- the dosing capacity of the dosing device is 1 12.5 1 per minute, after a pre-dosing time of 10 minutes approx. 12 to 14 kg of detergent powder are available.
- the tanks of the consumers 10 are connected to the ring line 8 via T-pieces and solenoid valves and metering hoses.
- the metering hoses are provided with throttles at the end that prevent ventilation and emptying.
- the filling of the tanks with detergent suspension is controlled via the solenoid valves.
- the dosage of detergent powder and water (usually 1:10) in the dosing device 1 is carried out via control devices. Further Control and monitoring devices are provided for the level control, the agitator 6, the centrifugal pump 9, the solenoid valves, etc.
- the invention is not restricted to the exemplary embodiment. Further modifications are conceivable without leaving the basic idea of the invention. In particular, it is also possible to attach a plurality of whisk bars in the storage container in order to further influence the flow profile in the container.
